To LLILWHOM IT'MAY oo NoEnN':

Be it kircwn that I, W. C. ROBINSON, of Saltsburg, Indianacounty, and tStateicf Pennsylvania, have` invented a. new and 4useful Improvement iuChurns'; and Ido hereby declare'thatthefollowing is a full and exact description 'of lthe same, reference being had. to the annexed drawings, an'dftheflettersof reference marked thereon, of which- Y' I v Y 1 Figure 1 is a perspective view of the churn, and-- Figure 2 a perspective view of the dasher and dash-stall'.

Like `letters refer to like parts in both drawings. y v

To enabletthose' skilled in the art to makeand use my invention, I'willproceed to describe its construction and operation. Y Y

' A is a .vessel for holding the cream; B is a cap ofthe vessel, which is supprted by an annular projection on theV inside of the vessel A, and is provided with a hole, a, 'suiiiciently large for the dasher-sta C to work vertically,- without friction. H is a dasher,.composed of'a lmlloweone, D, with perforations g g g, the frame 1i' F, and the hollow cylinder E. The hellowvperforated cone D is securely fastened to the cylinder E,"at its upper extremity c, and at its lower extremity by the frame F F, which is attached to the periphery of the cone D at d d d d, and to the cylinderE at e, and thedisl: G is also secured tothe cylinder E at e, and the whole firmly secured to the' staff bythe staii C passing through, and boing immovably compressed by the'cylinder E.

The operation of the churn -is asvfollows: The vessel A is filled about two-thirds full of cream, the dasher Dis inserted, and the cap B' is placedon the annular projection on the inside of'the vessel A, by f rst passing 'the staff C through the hole u, and lowering the cap B until itrrests in theposiftion, described.v In churning, sufficient motion should be given to the dasher D to raise it above the surface of the cream, so that the dasher causing theV best'd facilities for 4churnin comes infcontact and rcmoves'the 'cap B, when rolls or masses maybe take D may be filled with air, which, in .descending through the cream, isiorced out throufrh'the p and escapes'to the surface, thus,.with-the'agitation of-tlre cream produced by the dashe'rD and cross-frame F F,

g with rapidity and efficiency. Ehen the churning is finished, all the particles of butter rise to the surface ofthe cream. and are gathered into rolls or masses by gently tappingtbe cream on the surface with the dasherl-I, when the butter is collected.

n out to be worked'. Y 4 The churn may be cleaned by simply emptying the cream out of the`\-esse1 A, and substituting water, and

p replacing the' dasher D, and the cap B, and churning as before,

The simplicity ofthe construction. of this churn, and Athe .eiiicicncynndrapidity with which it operates, confidently recommend it to the public.

Having thus described the construction and secure by Letters Patent, is-

' -The dasher H, composed of the as and for -the purpose specified.

operation of my invention, what I olaimas new, and desire to perforated hollow cone D, the Aframe F'F, the cylinder E, and the disk G,
